Hereinafter, with reference to the accompanying drawings will be described an embodiment of the present invention;

1 is a diagram illustrating a configuration of a pacer device according to an embodiment of the present invention.

A pacer is a kind of reciprocating long running, and may be implemented as a user running in a reciprocating manner between the first cone 101 and the second cone 102. That is, the user located in the first cone 101 runs to the second cone 102 when the pacer tone sounds from the computing device 120, moves to the second cone 102, and waits at the second cone 102 position. If a beep occurs, the vehicle may move to the first cone 101.

The belt 110 may be attached to the chest of the user. The belt 110 may be attached with a heart rate sensor, an acceleration sensor, and a short range communication module. The heart rate sensor measures the heart rate signal of the user.

The acceleration sensor measures an acceleration signal corresponding to the pacer of the user. The acceleration signal may be distinguished from a signal while the user is running and a signal while stopping. That is, while the user is running, the amplitude of the acceleration signal may oscillate above a threshold value, and while the user is stationary, the amplitude of the acceleration signal may oscillate below the threshold value and be damped. have.

The first short distance communication module may be attached to the belt 110. The first short range communication module may transmit the heart rate signal measured by the heart rate sensor and the acceleration signal measured by the acceleration sensor to a computing device 120 through a local area network.

The computing device 120 includes a second short range communication module to receive the heartbeat signal and the acceleration signal from the first short range communication module. The first short range communication module and the second short range communication module may be implemented as one of a zigbee module, a Bluetooth module, an UltraWideBand module, a wireless USB module, and an infrared ray (IrDA) module.

The computing device 120 may be implemented as a device including an algorithm capable of calculating the number of pacers according to the present invention, such as a general PC or a notebook. The computing device 120 generates a pacer beep according to a predetermined schedule to guide the pacer of the user, and measures the number of pacers of the user through the acceleration signal received from the acceleration sensor.

The schedule may be implemented at a time interval for generating pacer beeps. For example, the interval between the generation of the first to seventh pacer tones may be implemented as 9 seconds, and the interval between the generation of the eighth to 15th pacer tones may be 8.2 seconds. According to the schedule, the computing device 120 may generate a pacer tone at each time to guide the user to perform the pacer.

The computing device 120 terminates generation of the pacer signal after the first time elapses when the amplitude of the acceleration signal is measured to be less than a predetermined threshold value for a first time after generation of the K th pacer beep. The number of pacers of the user can be calculated as K-1.

The first time may be implemented, for example, 20 seconds. That is, the computing device 120 determines that the user no longer performs the pacer when a phenomenon occurs in which the amplitude of the acceleration signal of the user is measured below the threshold value for 20 seconds after the generation of the pacer tone. When the first time elapses, the user's pacer may be terminated without generating a pacer tone for the user.

In this case, the computing device 120 may calculate the number of pacers of the user as K-1, which is the number of pacer tones generated before the K-th pacer tones occur.

Further, when the device measures the amplitude of the acceleration signal to be less than a predetermined threshold value for a first time after generation of the K-th phaser beep, the computing device 120 starts the K-th phaser beep from the start of the phaser. The number of damping of the acceleration signal occurring during the time until may be calculated as the number of pacers of the user.

In this case, it is possible to accurately calculate the number of pacers of the user who has performed the pacer twice in one pacer section without performing the pacer in one-to-one correspondence with each pacer number. That is, by measuring the number of pacers of the user according to the number of damping of the user acceleration signal, not the number of occurrence of the pacer signal tones, it is possible to accurately detect the number of pacers of a user who has performed a separate pacer without following the instruction of the pacer tone. Can be.

2 is a graph illustrating an acceleration signal of a user who performs a pacer according to an embodiment of the present invention.

The graph of FIG. 2 shows a first user according to a case in which a pacer tone generation interval of the first to seventh times is 9 seconds, and the pacer tone generation interval of the eighth to eleventh times is implemented as 8 seconds. The acceleration signal of the second user and the third user is shown.

In the case of the first user, the acceleration signal graph of the first user recognizes that one run is performed during one pacer period from 0 second when the first pacer tone occurs to 9 seconds when the second pacer tone occurs. can do. Thereafter, the first user may perform one pacing for each pacer interval up to eight pacer intervals and recognize that the pacer is no longer performed after the generation of the ninth pacer tone.

In this case, the computing device 120 determines that the pacer of the first user is terminated at 83 seconds after the first time 20 seconds has elapsed from 63 seconds, the ninth pacer tone time, through the acceleration signal of the first user. The number of pacers of the first user may be measured eight times.

In the case of the second user, the computing device 120 may detect that one run is performed for each pacer section from the first pacer section to the fifth pacer section. The computing device 120 detects that the second user's pacer is no longer performed for 20 seconds from 36 seconds when the sixth pacer tone occurs, and determines that the second user's pacer has ended in 56 seconds. The number of pacers of the second user may be measured five times.

In the case of the third user, the first pacer section, the second pacer section, the fourth pacer section, the five pacer section, and the six pacer section detect that one run is performed for each pacer section. However, since the damping of the acceleration signal occurs twice in three pacer sections, the computing device 120 may detect that two runs are performed.

Accordingly, the computing device determines that the third user's pacer is terminated at 65 seconds after 20 seconds have elapsed since the generation of the seventh pacer beep, and according to the number of damping of the third user acceleration signal, the third user's pay The number of cycles can be measured seven times.

As described above, the pacer device according to the present invention may measure the number of pacers of the user who performs the pacer according to the number of occurrence of the pacer signal sound, and the amplitude of the user acceleration signal is damped below a threshold value. It can also be measured by recovery.
